President William Ruto is among the leaders attending the funeral of Dagoretti South MP John Kiarie's father David Waweru.
The ceremony is being held at Kiranga primary school grounds in Kandara, Muranga.
Waweru succumbed to cancer on May 10.
Kiarie made the announcement in a tweet saying, "The Lion has rested. Dark, dark hour... As the 3 o’clock late afternoon sun battled with a stubborn dark cloud, for superiority in the skies, a stubborn dark cancer struck a final mortal blow. Death is so final, it is unbelievable.
He also shared a Bible verse, "Grief pierces to the core. Acts 13:26"
The deceased is a former Kandara MP and unsuccessfully vied for the presidency three times.
Waweru was the fourth MP for Kandara from 1981 to 1983 following the nullification of the election of the late Ndung'u Mwicigi.
He, however, decided to go for the presidential seat in the 1997, 2002, and 2007 elections but he lost.
